My WordPress site is ready for a visual upgrade: I want a clean, responsive lightbox gallery populated with well over 20 images that I will supply. Each image must appear in the appropriate category so visitors can quickly filter through the content. Here is what I need from you: • Select, install, and configure a reliable lightbox solution (for example → Fancybox, Lightbox2, or Envira Gallery—whatever integrates best with my current theme). • Upload and compress the images I’ll provide, assign them to their respective categories, and ensure alt-text is preserved. • Match the lightbox styling—fonts, colors, navigation arrows—to the rest of the site so it looks native. • Test on mobile, tablet, and desktop to confirm smooth transitions, swipe support, and quick load times. Once everything looks and performs flawlessly, send me a short hand-off note outlining how to update or add new categories myself.
